Grandstream Networks, Inc.

Grandstream Networks, Inc. — commonly "Grandstream" — is a privately held communications equipment maker founded in 2002 and incorporated in Delaware, headquartered in Boston, Massachusetts (its earlier corporate filings list Brookline, MA). It has additional US offices in Los Angeles and Plano/Dallas, Texas, plus overseas locations including Shenzhen and Hangzhou, China. The company is not publicly traded and publishes no audited revenue; its own fact sheets cite 300–400+ employees worldwide, while third-party data aggregators estimate roughly 200–500 employees and annual revenue in a wide, unverified range (about $55M to $185M). Those figures are estimates and should be treated as approximate.

Grandstream manufactures premises-based IP voice, video, networking, and physical-security hardware sold through distribution and reseller channels in over 150 countries. Product lines include SIP desk and cordless IP phones, video phones and conferencing devices, analog telephone adapters, analog gateways, IP PBX appliances, Wi-Fi access points, network switches and routers, hotel phones, and IP video surveillance cameras. It is an operating company with a real hardware and software business; patent databases list roughly 96 patents assigned to it, but it does not appear as a routine patent plaintiff.

Litigation posture: pure defendant. In the tracked case data, Grandstream appears in 2 cases, both as defendant and 0 as plaintiff, all in the Eastern District of Texas. Both were filed by CommWorks Solutions, LLC, a patent assertion entity associated with Georgia monetization firm IP Investments Group LLC (d/b/a IPinvestments Group) and publicly described by RPX and Stanford's NPE litigation database as a non-practicing entity. CommWorks asserts patents acquired from Intellectual Ventures LLC.

The tracked matters are CommWorks Solutions, LLC v. Grandstream Networks, Inc., the more recent filed 2026-09-04, with an earlier companion case in the same venue. CommWorks runs multiple overlapping E.D. Tex. campaigns before Judge Rodney Gilstrap — one covering Wi-Fi/WMM and wireless networking patents, another covering cloud PBX and fax-to-email technology — against networking and unified-communications vendors. Grandstream's exposure reflects its VoIP and Wi-Fi networking product lines rather than any offensive patent activity; no merits findings are recorded here.
